    Tosca, Nick; Masterson, Andrew (2014-04) - Journal article
    Mg-silicate minerals (e.g., stevensite, kerolite, talc, sepiolite) play an important role in the construction of facies models in lacustrine and peri-marine environments because they are sensitive to changes in solution ...
  • The continental record and the generation of continental crust 

    Cawood, Peter Anthony; Hawkesworth, Chris; Dhuime, Bruno Philippe Marcel (2013-01) - Journal article
    Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth's record of rock units and events is heterogeneous; for example, ages of igneous crystallization, metamorphism, continental ...

  • Hydrologic versus geomorphic drivers of trends in flood hazard 

    Slater, Louise Jeanne Elizabeth; Singer, Michael Bliss; Kirchner, James (2015-01-28) - Journal article
    Flooding is a major hazard to lives and infrastructure, but trends in flood hazard are poorly understood. The capacity of river channels to convey flood flows is typically assumed to be stationary, so changes in flood ...
  • The impact of the streamflow hydrograph on sediment supply from terrace erosion 

    Higson, John Lee; Singer, Michael Bliss (2015-11-01) - Journal article
    Sediment supply from banks and terraces has important implications for grain-size distributions in alluvial rivers (and by extension for aquatic habitat), as well as for the delivery of floodplain-stored nutrients and ...

    Slater, Louise Jeanne Elizabeth; Singer, Michael Bliss (2013-05) - Journal article
    Alluvial riverbed elevation responds to the balance between sediment supply and transport capacity, which is largely dependent on climate and its translation into fluvial discharge. We examine these relations using U.S. ...
